Risk Overview

About Natural Disaster Risk in Cattaraugus County, New York

Cattaraugus faces moderate disaster risk

With a composite risk score of 81.58 and a relatively moderate rating, Cattaraugus County sits above the national average in disaster exposure. While not in the highest tier, its risk profile warrants intentional preparedness across multiple hazard types.

Above average compared to New York

Cattaraugus's 81.58 score exceeds New York's 69.42 state average by a notable margin, placing it in the upper-middle range of the state's at-risk counties. This puts it above roughly half of all New York counties.

Higher risk than nearby Allegany

Cattaraugus County's 81.58 score exceeds Allegany County (69.75) to the south but falls below Chautauqua County (84.64) to the west and Broome County (87.47) to the east. The county's position in western New York's flood-prone terrain drives its elevated risk.

Floods are your primary concern

Flood risk stands at 89.92—well above state average—while tornado risk (68.35) and hurricane risk (68.13) present secondary concerns. Cattaraugus's location in a region of rolling terrain and river valleys creates seasonal flood vulnerability.

Secure comprehensive flood coverage

Flood insurance is critical given the 89.92 flood risk; check local flood maps and consider coverage even outside designated flood zones. Ensure your homeowners policy covers wind and tornado damage, and keep gutters and drainage clear before heavy rain seasons.
